Select OEM/ODM double-conversion and high-efficiency UPS platforms designed for critical infrastructures.
For modern computing architectures, industrial systems, and medical diagnostics, utility grids are prone to continuous instabilities. Standard emergency power supplies often introduce a minor millisecond latency (transfer time) during outages—a gap that can result in corrupted databases, process termination, or critical system failures. True "No Break Power" (otherwise known as double-conversion Online UPS topology) solves this by ensuring zero transfer time (0ms) between utility failures and battery reserve discharge.
By constantly processing electricity through a rectifier and inverter system, double-conversion online UPS units isolate your operational load from raw, unconditioned power. Fluctuations in voltage and frequency are eliminated. As a result, critical servers, medical equipment, and automation processors run on a synthesized, pure sine wave with absolute stability.
A global leader in standard and custom UPS power electronics engineering, research, and fabrication.
Shenzhen REO Power Co., Ltd. is a premier UPS manufacturer based in Shenzhen, China. Our engineering focus spans single-phase UPS systems, split-phase configurations (specifically 220V input/110V+110V output options), three-phase high-power units, lithium-ion UPS systems, modular rack structures, ruggedized outdoor systems, solar inverters, and high-discharge energy storage batteries.
With verified export capability to over 100 countries, we collaborate directly with B2B distributors, commercial project managers, and systems integrators in the medical, telecommunications, financial, and manufacturing sectors. We do not just build off-the-shelf power equipment; we develop tailored hardware and software adaptations that align with localized grid protocols and strict global compliance mandates.
Our design philosophy bridges the gap between raw manufacturing capability and regional application requirements. By aligning our hardware layouts and digital controller firmware with client specifications, we ensure that your product integrates seamlessly into its intended operating environment, optimizing performance and reliability.
We transform complex electrical engineering guidelines and specific branding requirements into market-ready, high-availability hardware platforms.
Deep engineering and software-hardware customization for unique environments:
Brand alignment and physical packaging structures to fit global channels:
Expert-led technical assessment for custom power hardware:
Operating 13,500m² of advanced production across dual manufacturing bases to guarantee capacity and quality.
Our dual-production bases housing 10 active assembly lines produce up to 80,000 units monthly. This large-scale output provides B2B buyers with consistent supply continuity even during peak market demand cycles. We control cost spikes through strategic raw material planning and localized component sourcing.
Every single UPS undergoes comprehensive quality control processes, including standard automated diagnostic cycles designed to prevent failures in critical field applications:
| Phase | Test Equipment Used | Core Focus & Metric Checked |
|---|---|---|
| AOI | Automated Optical Inspection | Validates SMT solder accuracy and component placement. |
| ICT & FCT | In-Circuit & Functional Testing | Checks voltage tolerances, current levels, and control circuit paths. |
| ATE Test 1 | Automatic Test Equipment | Pre-burn analysis verifying system parameters against design targets. |
| Burn-in | Thermal Chamber (8 Hours) | 100% of order units are stress-tested under full load (not batch-sampled). |
| ATE Test 2 | Post Burn-in Verification | Checks parameter retention and validates stable performance. |
| Environmental | Vibration & Thermal Chambers | Ensures ruggedness against shock and transport environments. |
Our production floor includes specialized testing resources, such as Constant Temperature & Humidity Chambers, RoHS Compliance Analyzers, and Vibration Tables. This helps verify that shipments conform to EN/IEC 62040 and local requirements before leaving the factory.
Our 96% on-time delivery rate is supported by direct connections to the Shenzhen and Hong Kong logistics corridors. This gives our customers flexible shipping options, including express air transport and container sea freight.
How REO Power Online UPS architectures are tailored to meet the strict demands of global B2B sectors.
Healthcare environments require zero-tolerance power protection. Imaging systems, life support devices, and MRI scanners cannot handle transient power anomalies or phase issues. The Maxwin Pro 3KW Medical UPS, combined with our isolated output designs, delivers clean power that conforms to medical safety standards.
Real-time banking platforms and central transaction hubs rely on high availability. Our Low Frequency Online UPS (6~30KVA) uses internal isolation transformers to block common-mode electrical noise and prevent grid disturbances from disrupting data integrity.
Server cabinets and processing arrays need scalable power distribution. Our transformerless high-frequency UPS units and 110V/220V rackmount systems offer high power density with a low spatial footprint. This configuration helps data center operators maximize cabinet density while lowering cooling overheads.
How REO Power is adapting to the next generation of industrial power architectures.
While traditional lead-acid (VRLA) batteries remain a common standard, modern installations are shifting toward lithium-ion backup systems. REO Power provides 110V and 220V lithium-compatible online UPS systems (1-6KVA). These batteries offer up to three times the life cycles of VRLA, lower weights, and stable performance at higher ambient temperatures, reducing the total cost of ownership (TCO).
Our newer three-phase systems use high-frequency insulated gate bipolar transistors (IGBTs) in active rectifiers. By removing the heavy output transformer, these systems achieve input power factor correction up to 0.99 and operational efficiencies up to 96%. This helps reduce energy losses during double-conversion processes.
Modern power systems need to be smart. Our product roadmap includes upgrading to high-speed dual Digital Signal Processor (DSP) architectures. These microcontrollers analyze and adjust inverter output in real time. Combined with network interface cards (SNMP), they allow IT staff to monitor parameters, check battery health, and run remote diagnostics through unified dashboards.
As commercial sites install onsite renewables, our hybrid solar inverters (3.5KW~5.5KW) bridge the gap between grid power, solar arrays, and batteries. These units dynamically route energy based on source availability and load requirements to optimize utility costs.
How we help global B2B clients manage regulatory requirements, grid differences, and supply chain complexity.
Electrical standards vary by region. We supply 110V single-phase systems for North America and Japan, 220V configurations for Europe and Asia, and split-phase systems (220V input to 110V+110V output) for specialized applications. Our biphasic systems with isolation transformers deliver clean, localized electrical connections.
All products are built to meet CE and IEC quality standards. Our manufacturing lines run according to ISO 9001 and ISO 14001 guidelines to ensure safety, performance, and environmental compliance for B2B procurement processes.
Industrial product customization requires clear technical alignment. Our R&D engineers communicate in English, allowing us to align on circuit design, firmware requirements, and technical specifications without misinterpretation.
